How to: Hide your data in a Audio Song

Introduction

Due to the way different file types are read it is possible to have a single file that acts differently depending on how it is read. For example sounds & images are read from the header down whereas ZIP files are read from the footer up.
All sound files should work, but some are more unpredictable that others. Mp3s seem to be the most reliable so this tutorial will be using them in the examples (plus who doesn’t love mp3 songs). All the steps are same if you want to use an image(.jpg) instead of sound.
